ADJUSIING DEVICE.

Application filed July 1S, 1923.

The invention relates to hardware of the kind which is usually employedin building constructions for controlling the movements of transomwindows, easement windows, sliding windows, ceiling lights, doors andthe like, and has for its object the provision of an improved adjustingdevice which is characterized in its construction, arrangement andoperation by certain hereinafter described features of novelty whichpeculiarly adapt the device for employment in suoli associations. Theadjusting device of the invention is also quite obviously susceptible ofemployment in connection with vehicles for regulating the positions ofcarburetor valves, heater valves, radiator shutters and the like.

The adjusting device requires the use of but one hand in effecting anadjustment of the transom window or other closure means with which thedevice is associated, is readily adapted to the structural peculiaritiesof any particular mounting surface which might ordinarily tend toconflict with the free operation of such a device, and is not subject tosuch localized wear as in time might act to impair the eiiieiency of itsoperation.

l/Vhile the foregoing statements are indicative of the nature of theinvention, other objects and advantages not herein specifically referredto will be appreciated upon a full comprehension of the novel featurespresented in the construction, arrangement and operation of the partscomprising the adjusting device.

In order that the invention may be readily understood, an exemplifyingembodiment of the same is set forth in the accompanying drawing and inthe following detailed description based thereon. Obviously theinvention is susceptible of embodiment in other and varied structuralforms without departure from the essence of the invention and withoutsacrifice of its material advantages; wherefore it is to be understoodthat the drawing and description are to be considered in an illustrativeand not in an unnecessarily limiting sense.

Fig. 1 is a front elevation of a transom window which is equipped on itsright-hand side with the adjusting device of the invention;

Fig. 2 is a view corresponding to Fig. 1, but shows a transom windowwhich is Serial No. 652,218.

equipped on its left-hand side with the adjusting device;

Fig. 3 is an enlarged front elevation of the adjusting device when inits locked position;

Fig. i is a vertical section through certain portions of the adjustingdevice on the line 4 4 of Fig. 3;

Fig. 5 is a horizontal section through the adjusting device on the line5-#5 of Fig. et.

Fig. 6 is a view which corresponds to Fig. 4:, but shows the adjustingdevice when in its unlocked position;

Fig. 7 is a horizontal section on the line 7 7 of Fig. 6; and

Fig. 8 is a perspective view of a clutch unit which forms a part of theadjusting device.

It will be observed in the drawing that the adjusting device 10, whenused for example in connection with a transom window 11, is mounted onthe door-frame 12 adjacent the hinged side of the door 13 with which thetransom window is associated, and operates to control the movement ofthe window 11 through the usual interposed mechanism 14C.

rThe adjusting device 10 includes a mounting. bracket 15, alongitudinally movable member 16 associated with the bracket, a handle17 at the lower end of the member for transmitting to the same either alongitudinal or a rotary movement, and a clutch assemblage 18 which iscontained within the mounting bracket and is adapted to lock the memberagainst further longitudinal movement in either direction upon themember being rotated by means of the handle.

The mounting bracket 15 consists of an interiorly serew-threaded tubularportion 19 and an integral attaching base 20 at one side of and parallelto the axis of the tubular portion.

The longitudinally movable member 16 consists of a rod which is ofnon-circular, preferably square cross section. The member need only beof such length that a portion thereof will remain within the bracketduring any extreme adjustment of the device, and is suitably swiveled atits upper end 21 to the lower end of an operating rod 22 adapted forreciprocatory movement in the mechanism li.

'The handle 17 may be of any desired type, and is advantageously onewhich extends radially from the lower end of the member a distancesuliicient to provide means for operating the adjusting deviceconveniently and without unnecessary el'liort.

The clutch assemblage i8 which is the teature oit the adjusting devicewherein the invention primarily resides, consists ot a plurality otintegrally associated clutch lingers 23 and an associated annular stop2e for coaetion with the clutch ingers. rllhe clutch fingers arepreferably termed in a single unit, but obviously may be formed inseparate pieces. rlhe single unit embodying the clutch lingers 23 has anaxial, preferably square passage which is adapted to encomaass themember in i` terlitting non-rotatale engagement therewith, and ischaracterized by a tapered nose portion 25 and an adjoiningscrew-threaded cylindrical portion :6 for screw-threaded engagement withthe bore ot the tubular portion of the braeln et. rlhe annular stop 2iconsists of a sleeve which freely encompasses the member 16 and isexteriorly screw-threaded for screwthreaded engagement with the bore otthe itulnllar portion ot the bracket. One end 27 of the sleeve has anannular portion which is engageable with the nose portion et the clutchunit to cam the several clutch fingers inwardly against the member whenthe nose portion oit the clutch unit is advanced in engagement with theannular portion of the sleeve upon rotation ot the member', and theother end 28 of tie sleeve has an enlarged polygonal portion for use inadjusting the position ot' the sleeve longitudinally within the bore otlthe tubular portion of the bracket. fr set-screw 29 may extend throughan aperture in the bracket into the bore ot the tubular portion thereofand bear against the sleeve whereby to lock the same in any desiredposition.

The operation of the adjusting device is as follows:

When the handle is in the position shown in Fig. G, the clutch lingersare tree from frictional engagement with the member regardless ot theposition of the member longitudinally of the bracket, but, when thehandle is turned to the right into a position substantially parallel tothe plane of the base as shown in Figs. 3 and 4, the clutch lingers areturned with the member and, being in screw-threaded engagement with thebracket, are advanced against the end portion oi the sleeve and cammedinwardly by the same against the member whereby to lock the memberagainst further longitudinal movement in either direction. ln order torelease the member and permit further longitudinal movement of the same,it is only necessary to turn the handle in a reverse drection until theclutch lingers have been unserewed suliiciently Aaway trom the sleeve topermit their expansion and disengagement'i'rom the member. rlhe sleeve,be-

tf1. pomY `ing to the rigl t when locked in a position t removed aspossible trom the path o t ie door. ln order to adapt the presentadjusting device tor use with a door which is hinged along its lett-handside as shown in 2, the bracket with its associated clutch need only bereversed as an entirety when being mounted on the door traine, whereuponthe device will lock the member tinst further longitudinal movement uponbeing turned to the lett away trom the door.
